multipart/form-data

Multipart/form-data is a format used when submitting forms on the web, especially when uploading files. Unlike standard forms that send data as plain text, this format allows multiple types of data—like text fields and files—to be sent together. Each part of the data is separated and includes its own headers that describe the content. This enables web applications to handle complex data submissions, such as user details and file uploads, efficiently. It's commonly used in scenarios like submitting images or documents through websites.
